By no means are better background agents "mythical" as you claim. I didn't bother to mention them as it is easy enough to search for asynchronous/background agents yourself.
Devin is perhaps the one that is most fully featured and I believe has been around the longest. Other examples that seem to be getting some attention recently are Warp, Cursor's own background agent implementation, Charlie Labs, Codegen, Tembo, and OpenAI's Codex.
I do not work for any of the aforementioned companies.
